Titanium dioxide (TiO2) nanoparticles are ubiquitously used materials in everyday life (e.g. paints,household products and plastic goods). However, despite the wide array of common applications, their pathogenetic role was also suggested under certain conditions pulmonary neoplasias lung fibrosis). From a dermatological point view, it is great importance that TiO2 serves as physical photoprotective agent sunscreens widely various cosmetic products. effect on human cutaneous functions still...
Background and Purpose— Several factors have been held responsible for the development of atherosclerosis. To avoid masking effect age, we evaluated correlates carotid atherosclerosis in patients <55 years age. Methods— Plasma lipids, oxidative resistance low-density lipoprotein, homocysteine, inflammatory markers, plasma viscosity, red cell deformability were measured fasting blood samples 100 subjects: 45 with >30% stenosis internal artery, 20 occlusion, 35 control subjects. Stenosis...
Neolithic artifacts made of nephrite, □Ca 2 (Fe,Mg) 5 Si 8 O 22 (OH) , are found at prehistoric settlements in Bulgaria. This study investigates these objects based on particle induced X‐ray emission using a scanning nuclear microprobe (micro‐ PIXE technique). Seven nephrite from the sites Kovachevo, Bulgarchevo and Galabnik southwest Bulgaria were analyzed to quantify their composition establish if correlation exists between distribution major trace elements, color, impurities, texture. The...
A novel in-air PIXE (Particle Induced X-ray Emission) setup was developed which is capable of the fast, sensitive, fully quantitative characterization elemental composition thin and thick samples for elements with Z > 6.
Abstract In this study, the identification of PM sources during smog episodes in Debrecen is presented. The were characterized by high concentration 10 , and linked to a thermal inversion period November 2011 Hungary, when an anticyclone occurred across Europe. 2.5 coarse identified positive matrix factorization (PMF). Additionally, source locations explored using conditional probability function (CPF). A numerical weather prediction model (WRF) was also applied evaluate air pollution...
Abstract In this study, atmospheric aerosol concentration levels in two schools (a primary and a secondary grammar) kindergarten were investigated. The selected institutions are located close to the center of Debrecen, where traffic density is rather high. Coarse fine mass concentrations (PM), elemental composition size distributions determined microenvironments. These different classrooms, school yards, gymnasiums, computer lab, chemical lab so‐called salt room. (for Z ≥ 13) was by PIXE....
Abstract Ion beam analysis plays an important role in cultural heritage (CH) studies as it offers a combination of simultaneous and complementary analytical techniques (PIXE/PIGE/RBS) spatially resolved mapping functions. Despite being considered non-destructive, the potential risk beam-induced modifications during is increasingly discussed. This work focuses on impact proton beams parchment, present our CH form unique historical manuscripts. Parchment one organic, protein-based materials...
The worldwide restrictions due to the COVID-19 pandemic induced a radical change in urban air quality. objective of this work was study and understand variation PMcoarse PM2.5 pollution besides other quality (AQ) parameters city Debrecen, Hungary from 2018 2022. To achieve goal, we introduced an integrated approach that combines source apportionment by receptor modelling, trajectory-based statistical methods takes into account local regional meteorology. Concentration, elemental composition,...
The paper introduces the particle-induced X-ray emission analysis (PIXE) of two Hajdúböszörmény-type situlae from eponymous Hajdúböszörmény I hoard (collection Hungarian National Museum, Budapest) and Sényő Jósa András Nyíregyháza). Both are representative types period between 1080 960 BC, Ha B1, or ‘Hajdúböszörmény horizon’ Late Bronze Age. obtained results significant in that they very first to characterise classic situla their core distribution area, i.e., region where this metal vessel...
